[0001] The utility model belongs to the technical field of biomass fuel particle production, in particular to a biomass fuel particle forming device. Background Art

[0002] Biomass pellet fuel is actually the direct combustion of biomass energy, which is the processing and utilization of biomass. Direct combustion methods can be divided into four types: stove combustion, boiler combustion, garbage combustion and solid fuel combustion. Among them, solid fuel combustion is a newly promoted technology. It solidifies biomass into a shape and then uses traditional coal-fired equipment to burn it. Its advantages are that it makes full use of biomass energy to replace coal, reduces CO2 and SO2 emissions, is beneficial to environmental protection and controls greenhouse gas emissions, slows down climate change, and reduces the occurrence of natural disasters.

[0003] When the existing biomass fuel particles are pelletized, the molding equipment is not convenient to disassemble, clean and maintain, which makes the maintenance of the equipment difficult. In addition, the equipment structure is relatively complex and the cost of the equipment is high, which is not conducive to promotion. For this reason, we proposed a biomass fuel particle molding device. Utility Model Content
